Metasurfaces for colour printing
2014
We present a theoretical analysis and experimental evidences of metasurfaces based on particle resonators that achieve bright-field colour prints. We created pixels that support individual colours, miniaturized and juxtaposed at the optical diffraction limit. Different strategies are followed to offer the flexibility of using both transmitting and epi (reflective) white light sources. We discuss their potential applications in large-volume colour printing via nanoimprint lithography.
HOLONIC PRODUCTION SYSTEM TO OBTAIN FLEXIBILITY FOR CUSTOMER SATISFACTION
2008
The Holonic Production System (HPS) can be a valid choice to overcome the problems of traditional production sys-tems’ architectures, thanks to its capability to adapt and react to changes in the business environment whilst being able to maintain systemic synergies and coordination. The HPS is made of holons seen as functional production units which are simultaneously autonomous and cooperative. Although the holonic approach could represent a valid solution in order to pursue the necessary levels of agility of production systems, they have been scarcely implemented in practice and even less studied from a business studies perspective. The purpose of this discussion paper is to show the bene…
Computerized dynamic fluid simulation (CFD) for measuring the influence of the cab deflector on the aerodynamics of trucks
2021
This paper refers to how the cab deflector of trucks can influence the aerodynamic coefficient. The first part of the paper includes some generalities taken from previous studies, regarding the types of solutions to improve aerodynamics for trucks. The second part of the paper is a more practical one and has two main chapters: modeling and simulation of modeled parts. In this sense, a truck and 3 cabin deflectors were schematically modeled in Catia v5. After assembly in the Catia v5 program, the impact of the cabin deflector was analyzed. Thus, a computerized dynamic fluid simulation (CFD) was performed using the specific module in Ansys. The simulation included the CFD analysis of the four…
Evaluation of methods aimed at complete removal of template from molecularly imprinted polymers
2001
Polymers imprinted with clenbuterol were used to study the influence of various post-polymerization treatments [e.g., thermal annealing, microwave assisted extraction (MAE), Soxhlet extraction and supercritical fluid template desorption] on the bleeding of residual template. The aim of the study was to reduce the bleeding to levels that would allow the use of the materials as affinity phases for extraction of clenbuterol from bovine urine at concentrations below 1 ng ml−1. After treatment, the clenbuterol imprinted polymers were packed into solid-phase extraction columns and the bleeding was estimated by quantifying the amount of template released in 10 ml of methanol–acetic acid (9 + 1 v/v…
Effectiveness of Entrepreneurial Universities: Experiences and Challenges in Digital Era (A Systemic Approach)
2021
The modern world actively discusses the challenges that will lead to the Fourth Industrial Revolution. As the specialists assume, part of the jobs will be replaced by artificial intelligence. In addition, creation of completely new jobs is expected. As for the jobs that might be maintained in future, skills upgrading will be particularly important. In such a turbulent environment of economic development, universities, and in particular entrepreneurial universities, play a significant role. We think so as these universities have special structures that promote form a university-industry-government triple helix, reskilling and commercialization of new ideas, etc. Due to the above-mentioned fa…
Come l'amore per la verità interpella la funzione imprenditoriale e quella di docente universitario
2010
L'articolo propone alcune riflessioni stimolate dall'enciclica Caritas in veritate. Si cerca di considerare in che termini la verità opportunamente specificata al contesto in oggetto contraddistingue la funzione imprenditoriale con evidenti richiami alla dimensione etica degli affari.
Mixed e-assessment: An application of the studentgenerated question technique
2010
This paper presents the experiment of a mixed summative-formative evaluation in an asynchronous distance higher education context. In the experiment, performed in the distance course of Total Quality Management, Industrial Engineering, University of Guadalajara (Mexico), students are guided to formultate questions on specific topics. Studentgenerated questions are evaluated through an ad-hoc quantitative tool, specifically designed for the purpose: the four-criterion Observation Matrix. The experiment shows: (1) that it is possible to improve the Higher Education evaluation process and formalise students' skill in a more thoroughly way than with traditional evaluation; (2) how the student-e…

Qualitative study about group music therapy experience of young musicians dealing with music performance anxiety
2015
Few studies have looked or presented the meaning of music performance anxiety from the viewpoint of young musician´s. Whereas most of the studies conducted were quantitative, this study used qualitative approach of phenomenology. The aim of this study was to investigate the experience of young musicians dealing with higher amount of music performance anxiety in clinical music therapy group. The study addressed questions about the role of the group, shared experiences in music and the role of free discussions in therapy. Free-flow musical improvisation was the most frequently used clinical technique. Five young musicians took part of 12-weekly group therapy sessions during 5 month period. Ba…
Game theory as a marketing tool: uses and limitations
2011
The growth of complexity of the business environment in which firms operate, calls for more effective tools, able to consider the effect of the strategic choices of the actors of the market and to supply information useful for managerial decision process. Game theory seems to be an ideal candidate for this scope. Nevertheless, because of its axiomatic approach, its validity to highlight and define marketing issues has many critics. This paper analyses the main literature about the use of game theory for marketing management decisions and highlights its limits in this field in order to answer to the question: Can game theory be an effective marketing tool?
